• FIG. 8 A further embodiment is shown in Figure 8.
• a shaver handgrip 80 has fitted thereto a sterile shaver blade 82 which, similar to the embodiments described in the foregoing, includes an information carrier 83 which, when the shaver blade 82 is fitted, is located opposite a reading element 84.
• FIG. 9 Another embodiment is shown in Figure 9. This embodiment is very similar to the one shown in Figure 1 but in this case the hose part 4 is fixedly connected to a cassette part 17, being provided with an information carrier 9, located opposite to the reading element 12 on the equipment.
• Figure 10a and 10b are sectional views of the identification device.
• a cassette part 17 is firmly fixed to the holder 8.
• An information carrier 9 is situated in the holder. It will also be seen that the holder is mounted in the fixation seat 7 and that the information carrier 9 is situated opposite the reading element 12, which is firmly fixed in the fixation seat 7.
• Figures 10a - 10b illustrates the sequence of events taking place when the holder 8 comprising the firmly fixed cassette part 17 is fitted or mounted in the fixation seat 7.
• the surface 21c is in abutment with a corresponding edge surface in the seat 7.
• Fig. 10a shows how the holder 8 is firstly moved towards the fixation seat 7, and thereafter placed as depicted in Fig 10b.
